-- Alberto Caeiro tells us that "in the city, the great houses Close the View by key, hide the horizon, (...) and make us poor because the only wealth is to see."

This idea helps to realize that with growth of São Paulo, our memory impoverished Circuits, buildings, monuments, sounds, practices, gestures and other elements of the urban landscape and the experience of its inhabitants disappeared. Lost the collective memory as the family residence in the eighteenth century, occupied the end of the current Sink Street.In some cases, the city reconfigurations led to the true ground zero memory: spaces where the symbolic wear reduced the past to ashes.The approach of the art in these blind spots can stimulate our perpepção for such processes. For example, the sculpture "Spiral Jetty" by American artist Robert Smithson, tensions the salinification a lake as its isolation from current water sources after the construction of a rail spur.The accumulation of rocks used by Smithson in the work and the increased salinity of the water, because of interference on the social environment, living metaphorically. These considerations allow us to address the work "A reflection on irregular cycles," Victor Leguy of very particular way.Designed for the space of the old incinerator Pinheiros, the work presents the story enclosed underground on site. The existence of toxic elements resulting from waste incineration has the improper area to socialize, just taken to the revitalization initiative that originated the Victor Civita Square.The big gray pockets buried there, now isolated from the contact of visitors emerge from the work as recontamination elements: on entering the black ashy room, we take contact with the burnings - concrete or symbolic - that operate in daily life, the small gestures we insist to ignore and the memories we prefer not to read.Thus, the work of Victor reminds the city of Argia, which appears on the Italo Calvino’s novel, "Invisible Cities". Argia, describes Calvin, is a city where land replaces the air, where "the streets are completely filled with earth, clay fills the rooms to the ceiling."But, the author warns, if we, on the surface on Argia, pull over ears on the ground, we can hear, downstairs, port knocking noises.————-
